Frequently asked questions
CosmoLex scores F on the API Report Card. No public REST API, developer portal, OAuth, or webhooks. The only programmatic surface is the official Zapier connector with nine triggers and seven create actions; there are no read, update, or delete operations. Storage, e-sign, and payments hookups are fixed point integrations.
Without a usable official API, teams fall back on manual exports, file drops, or one-off vendor integrations. The other option is an unofficial API layer like Supergood that automates the authenticated web app directly.
CosmoLex is a cloud-based, all-in-one law practice management platform that bundles matter management, time tracking, billing and invoicing, document management, calendaring and tasks, client intake, e-signature, and, uniquely among LPM competitors, fully integrated three-way trust accounting and business accounting (no separate QuickBooks required, though a QuickBooks Online sync is offered).
Legal, specifically solo attorneys and small-to-mid-sized law firms (roughly 1–25 attorneys) in the U.S. and Canada that need trust/IOLTA accounting compliance baked into their practice management system. Attorneys and paralegals open matters, log time and expenses, generate and send invoices, accept LawPay/LexCharge online payments, and run trust deposits, disbursements, and three-way reconciliations directly inside the app.
Medium-high within the U.S./Canadian solo & small-firm LPM segment. CosmoLex is consistently named in the Clio / MyCase / PracticePanther / Smokeball / CARET Legal competitive set across G2, Capterra, and analyst comparisons, with hundreds of verified reviews on each.
CosmoLex sits on the entire operational and financial nervous system of a law firm: every matter file, client and contact record, conflict-check history, every time entry and expense, every invoice and payment, full IOLTA / trust ledger with three-way reconciliation, business general ledger, matter budgets, document index (with documents themselves often synced to OneDrive/Google Drive/Dropbox/Box/NetDocuments), calendars, tasks, notes, and intake forms.
Mid-mature. Launched in 2013 as a cloud-native, accounting-integrated LPM, a genuinely modern proposition at the time, CosmoLex is now 12+ years old and on its third corporate owner (independent → Tabs3 → ProfitSolv).

Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
Yes. Supergood maintains an unofficial CosmoLex API and MCP server so AI agents and internal tools can read and write CosmoLex data. See the CosmoLex integration docs at supergood.ai/docs/cosmolex-api.
